Technical Abstract

Disclosed herein are methods and systems for painting driving assistance markings using one or more paint materials which are visible in a plurality of light spectral ranges, in particular, visible light and one or more infrared light spectral ranges. Further disclosed are methods and systems for analyzing images captured in multiple spectral ranges to identify the driving assistance markings and/or part thereof in a plurality of different spectral ranges and identify aggregated driving assistance markings by aggregating the driving assistance markings identified in the plurality of different spectral ranges. Also disclosed herein are methods and systems for presenting and detecting enhanced driving assistance markings on one or more elements under one or more paint materials which are highly transparent in one or more infrared spectral ranges while reflecting visible light conforming to a color of the element(s) surface thus not affecting appearance of the element(s) in the visible light spectrum.

4. The method of claim 1, wherein the plurality of spectral ranges are members of a group consisting of: visible light having a wavelength in a range of up to 700 nanometers, near infrared (NIR) having a wavelength in a range of 700-1000 nanometers and short wave infrared (SWIR) having a wavelength in a range of 1000-3000 nanometers.

5

5. The method of claim 1, wherein the certain value equals 15%.

7

7. The method of claim 1, wherein the at least one element is a member of a group consisting of: a section of the at least one road segment, a colored mark printed on the at least one road segment and an infrastructure object located in proximity to the at least one road segment.

10

10. The method of claim 9, wherein the first value equals 15% and the second value equals 85%.

11

11. The method of claim 9, further comprising the enhanced driving assistance markings are encoded.

12

12. The method of claim 9, wherein the enhanced driving assistance markings are painted on the surface under the at least one paint material.

13

13. The method of claim 9, wherein the enhanced driving assistance markings are displayed by at least one display device having a screen surface painted with the at least one paint material.
